does it have sag ?if you're set on the hw and the mk3 you could build it and lay it on its side. i was dead set on the hw at first, but i ended up building the db. 2 db-12s are, imo better than a hw with 2 12s.

when i read the onld db forum, i found one of steve's posts saying that 2 db-12s (1 woofer in each) would perform better than 1 hw with 2 woofers. sag is related to moving mass (voice coil + former + cone) and suspension stiffness. post some specs, i'll see if i can help you.

[/quote]ive built both in a 12 inch version, i wouldnt say either is better, dbs a little cleaner, hwk has more output.

*edit* Sorry to keep bumping my post, but according to PE's calculations, the 15" Dayton Series II (which is so popular here) has approximately 8.6% sag, while the 15" Titanic MKIII has approximately 3.05% sag.

PE states "As a general rule of thumb, any time the sag exceeds 5% of the driver's Xmax, it's not recommended for a down-firing subwoofer application"

It looks like the Series II isn't such a good choice in a vertical HW... ???

Wreckin', I don't understand what you wrote. Are you backing what Adrian (and Steve has) said about 2 db's being "better" than 1 dual-loaded HW? How is a dual-loaded, magnet-to-magnet, HW not "utilizing the cone area of both speakers"?

When I'm really troubled by something I go to the bathroom, sit there, think about it, and the answer materializes out of nowhere it seems. Weird.....

How is a dual-loaded, magnet-to-magnet, HW not "utilizing the cone area of both speakers"?[/qu Think about it, the speakers are lined up back to back or front to front as the case may be. In this configuration you must wire the speakers out of phase with one another causing them to work as one. This configuration will without a boubt give you more control and tighter bass, but you will still be using the cone area of one driver 176.71 square inches. By using two single loaded cabinets you are utilizing more cone area 226.20 inches. The difference in cone area is approximately the equivalent of an 8" woofer. Pump one fist in the air you have your HW, pump 2 fists in the air you have your Db's. Get it?
